i have a '06 F650 cummins flatbed that has has a mystery loss of power to the right lowbeam headlite. Have not been able to determine if it's in the harness or the switch. Any one else had this issue? Where or what may I have overlooked? Any help is Appreciated!
Thanks Rick

If it is just the one headlight it may be a bad ground for that specific headlight if you open the hood look at the harness one wire should go to ground. Other questions does the highbeam work and does it look dim if it does work?

This truck uses seperate fuses for the right and left low-beams. CJB fuse 26 is for the left headlamp, and fuse 28 is for the right headlamp. That being said, Blue Diamond trucks have horrible wiring harnesses. Look around the hood harness for signs of "green-death" poking through the tape. Also, you can check to see if you have power at the dark green and orange wire at the connection to the hood harness to determine where the issue might be.
